This invention relates to circular knitting means for producing patterns of various shapes and sizes by a two color effect in a knitting machine wherein two threads are fed in a plating relation.

This application is an lmprovement upon the construction shown in the co-pendmg a p plicationl of Frank E. Jones, Serlal o. 92,746.

In order that the princi le of the inventlon may be readily understoo we have'disclosed in the accompanying drawings improved means for producing patterns by color eiect in plated work.

In said drawings,- l

Our invention relating, as 1t does, to circular knitting machines may be applied to or embodied in various types o'fsuch machines,

but we have chosen to represent the same as applied to a machine of the well-known Banner type disclosed in the patent to Joshua D. Hemp ill, No. 933,443, dated September 7, 1909. In this type of machine the needle cylinder rotates while the cams remain stationary and, although the machine disclosed is for the purpose ofproducing hosiery, it is obviously not limited to this class of'work. We will, however, describe our invention as applied to a machine of such type without limiting it thereto excepting when expressly so stated in the claims.

Generally speaking, the machine includes a rotating needle cylinder 1, mounted upon a suitable table 2, constituting a part of the frame of the knitting machine and, as is customary in this type of machine, said cylinder is arranged to be rotated to form the leg and and toe of the stoc ing,

The means for effecting the rotary and reciprocating movements are substantially the same as those shown and described in the said Hemphill patent and, being well'known, require no further description. i'

A. plurality of yarn `:feeding elements is foot and to be reciprocated 'to form the heel provided at the usual position characteristic ofJ the Banner machine, and a seriesot` said elements is indicated at 3 in` Fig. 6 and one,

of them is indicated at 3 in Fig. 7. 'Desirably as many as four orfive yarn guides may be mounted side by side at the same place each to introduce a yarn or thread as called for by the controlling cams, as, for example, for the leg, the heel and toe, All of said yarn guides are pivoted at 4 u on a latch ring 5 itself suitably pivoted, so t at it may be swung up out of action to afford access to the needles or for any other purpose. Since the particular t pe of machine here shown is the latch nee le ty we have represented the member V5 as a atch ring, but if the machine be c uipped with spring beard needles, as it ma e within certain aspectsv of and the foot, etc.

,our invention, tien the member 5 is in the form of a partial ring aswell understood in this art.

levers suitably mounted upon the standard rising from the bed plate 2, and need not -be more particularly described. The levers and connecting wires are provided in the general mannerV disclosed in said patent, and said levers are generally indicated at 6 in Fig. 2. They ride respectively upon suitable cams indicated at 7 in Fig. 2 upon a drum 8 on a cam shaft 9 in a manner not herein necessary to describe in detail, being desirably similar to the construction shown in said Hemphill patent. Assuming that there are four or five levers in the said group, it is evident that, according tothe dictates of the cams 7 upon the disk or drum 8, the said yarn guides are permitted to act in suitable order, as, for example, to supply yarn or thread for the leg of the stocking, another for the heel, another for the foot, etc.

Each of the said yarn guides sup lies its own yarn or thread in proximity to t e knitting point, and each yarn so taken is knitted upon all the needles in action unless there be a stitch variation to make a pattern effect.

Such stitch variation, in the disclosed embodiment of our invention, is produced by causing the desired needles to take only one of the threads so that the other thread is floated for short distances in making the pattern.

The machine is provided with the usual driving shaft 10 having the customary pulleys 11, and in the rear thereof is a shaft 12 driven from the shaft 10 and having fast thereon the large gear 13 known as the 104 gear. Controlled from the shaft 12 is the usual quadrant 14 pivoted at 15 and operated in a manner not herein necessary to describe in effecting the reciprocation of the needle cylinder for forming the heel and toe. These parts being desirably of customary construction here need no further description.

The machine is provided with the usual narrowing ickers mounted as customary upon a bloc indicated at 16 in Fig. 2 and with the customary Widening pickers, one of which is indicated at 17 in Figs. 2, 7 and elsewhere, being mounted upon a suitable bracket 18, preferably of usual construction.

Having thus referred to the main parts of the usual mechanism of the plain or rotary Banner machine, it is pointed out that our invention, shown for convenience as applied to such type of machine, is: concerned particularly with the formation of pattern effects in the fabric. While said pattern effects may be of the general character indicated in the said application of Frank E. Jones, we have herein, for purposes of illustration, chosen to represent or describe the pattern effect yas produced as a color effect secured by introducing at least two yarns which, at times, are so controlled as to produce plated work, at other times but one of tern said yarns being taken by a needle or needles, so as to produce a different color effect.

Merely for convenience of description we shall refer to the pattern as the diamond pattern, but it is to be understood that within the' principle of the invention the patis obviousl varied within wide limits, as to bot shape and size, and also as to position upon the stocking or other fabric. The needles, which it is unnecessary to show in detail, and which are desirably like those shown in the said Jones application, are in the disclosed embodiment of the l invention of the latch needle type, but they may be of the spring beard type, in which case suitable pressers and other cooperating parts are employed. v

Each of the needles is mounted as is customary within its groove in the needle cylinder, and said cylinder, as clearly indicated in the figures of the drawing, is of increased height so that the grooves may be prolonged below the needles and receive in each of them a controllingj ack 19, a group whereof is represented in igs. 15 and 16.

The said jacks are distinct from the needles and are mounted so as to be reciprocated with suitable friction Within their grooves by the cams to be hereinafter described, and they -in vertical alignment according to the pattern effect to produced, and the various jacks so differentiated among themselves are distributed in the proper needle grooves, so as to secure the proper pattern by elevating their respective needles at the proper time. In the selected embodiment of the invention the butt formation of the jack is the same as in said co-pending a plication. Briefly stated, all of the jacks 19li 20. Certain of said jacks have thereabove a second butt 21; certain only of the remaining butts have thereabove a butt 22; certain of the remainin butts have thereabove a butt 23; certain of t e still remaining butts have thereabove a butt 24; and certain of the still remaining butts have thereabove a butt 25. Such butts as are present upon any one jack' are verticall spaced, as clearly indicated in Figs. 15 an 16.

The said butts 20 to 25 inclusive are adapted to be acted upon by a series of cams 20a, 21a, 22a, 23a, 24a, 25a, as shown in Fig. 7 and elsewhere, and adapted to act substantially as shown in said co-pending application. Said cams are mounted one above another as herein more fully described, and are capable of movement into and out of engagement with the respective butts controlled thereby, such movement being -preferably a radial one with reave the lower buttsv spect to the axis of the needle cylinder. .The function of the cam 20a is to effect the raising of all the needles, and in this embodiment of the invention all the jacks are provided with butts 20. The remaining cams (namely, 21a to 25a) are selecting cams to act upon the jack butts similar in number, so as to elevate the needles -pertaining thereto for the reception of the plating yarn. We have not attempted to show a development of the knitting cams or the said selecting cams in such a development but it is to be understood that the cams may he in this respect substantially as shown in said co-pending application.

When a attern eifect is to be produced by a color e ect, as by plating, we introduce through the two yarn guides or fingers, two

yarns of contrasting color or nature in a plat-- ing relation, as, for example, a white yarn and a red yarn, and the tension condition thereof is desirably such as to produce a plated effect when both yarns are taken by the needles.

The needles which are not elevated, because of lack of a butt formation upon the jack at the determining point or level, will therefore take only the red yarn in the present instance, being so low when they pass the white yarn that t ey miss the same. The needles whose jacks ave butts calling for elevation in effecting the pattern would in such instance take the red yarn and immediatel thereafter take the white yarn,.and thus e fect a plating operation as the stitch is comleted. p Unless -a needle is elevated by its jack, it moves alon its lower level so as only to enga e the re yarn and after taking t e same is epressed 1n the usual manner. If, how,- ever, the needle is elevated through the action of a selecting cam on its jack, then it passes alon -at sufficiently higher level toV take the re yarn as well as the white yarn, and plating results. It will be understood, of course, that the shape or outline of the pattern effects may be varied as desired. In Fig. 1 we have represented upon an enlarged scale two threads (namely, a white thread 26 and a red thread 27). At desired points the white thread 26 is floated so that the red thread 27 appears in lengthwise stripes. Other patterns may be provided as desired. When both threads 26 and 27 are knitted,they appear in a lated relation. Y

n said application Serial No. 92,746, there is disclosed a small upright drum or barrel' mounted upon the bed plate. .In order to give greater pattern eiect we have substituted for said drum or barrel a series of chains, which are indicated at.28, 29, 30, 31and 32, in Figs. 9 to 13, and elsewhere. Said chains, as indicated in side elevation in Fig. 14, are mounted upon a drum 33 suitably supported upon the framing 2 of the machine in sucha manner that the said chains may be rendered taut,

and also upon another drum 34 which is suitably mounted upon the framing 2 of the machine nearer the needle cylinder.

The pattern chains are adapted to be driven in a step-by-step manner, and we provide means, under the control of the main pattern means of the machine, whereby the movement of said pattern chains 28 to 32 is interrupted whenever desired. For this purpose, and without limiting ourselves thereto, we have provided the following mechanism.

The main pattern chain of the machine, mounted in the usual manner, is shown at 35 in Fig. 4, and has an upward direction of travel viewing said ii ure. Upon said chain o are provided certain inks or lugs 36 which, in the movement of said main pattern chain, are adapted to ride under a projection 37 upon a lever 38, indicated also in Fig. 2, and to which is connected a bent wire 39 itself connected to a lever 40 pivoted at 4l upon the framing and having a long horizontally extending arm 42.

Jointed at 43 to said lever arm 42 is a depending strap-like member 44 having a flange or right-angled part 45 at its lower end adapted to take under, and at times to lift, a lever 46 pivoted at 47 upon a constantly rocking lever arm 48 itself mounted on the quadrant shaft 49. When said lever 46 remains in its.lowermost position, its hooked end 50 engages teeth 51 upon a ratchet wheel 52 pivoted at 53 upon the framing and turns the same in a step-by-step manner.

. The said ratchet wheel is provided with a series of spaced pins 54arranged in a circular series and adapted to be brought successively into engagement with the linclined edge 55 of a lateral enlargement upon an upri ht rod or member 56 which is mounted an positioned for vertical movement, it being guided by the pivotal screw or pin53 received in the lengthwise slot`57 and also by the screw or pin 58 in the lengthwise slot 59 in said rod 56. The impingement of apin 54 upon the inclined edge 55 results in a slight lifting movement of said rod 56 at times determined by the link 36 upon the main pattern chain 35.

To the upper end of said rod 56 is secured at 60 another rod 61, which extends vertically and is rovided with a collar 62 surrounded by a coiled spring 63 tending to depress said rod. The upper end of said rod 61 is pivotally connected to a lateral extension or arm 64 on a rock shaft 65 horizontally supported in suitable bearings 66 in a bracket on the bedplate 2.

Through the said connections the shaft is adapted to be turned at intervals depending upon the links or lugs 36 upon the main patternchain 35.` -If said shaft 65 is not so turned by the rod 61 and its connections, said rock shaft 65 is, under the control of a vertical rod 67 ,guided in the framing and adapted to be moved vertically by a cam 68 7 5- co-axially with the drum 34.

1 turn the same in a step-by-step manner.

co-axial with the 104 gear 13 at each revolution of said gear, as illustrated in Fig. 4. To this end, the said rock shaft 65 is provided with a ,lateral lug 69, shown most clearly 1n Figs. 4, 5 and 6, which, when said shaft 65 is not turned by the rod 61, rests upon the upper end of the upright rod 67, with the result that said shaft'65 receives a rocking impulse once for every rotation of the 104 gear. The purpose of rocking the shaft 65 1s to impart lengthwise or traveling movement to the various pattern chains 28 to 32.

Secured to the said rock shaft 65 at 70, as shown in Fig. 4, is an arm 71 to which is pivotally connected the rod 72, shown also in Figs. 6 and 8. Said rod 72 is positioned` horizontally, and at its opposite end has ivotal-lyconnected at 73 a lever 74 pivote at ivoted at 76 to the opposite end of the lever 74 is a pawl 77 to engage teeth 78 upon a ratchet fast with the drum 34, and thereby acting to hold back pawl 79 may be provided, if desired.

By the described connections, the said drum 34 with its chains 29 to 32 is constantly moved 1n a step-by-step manner, excepting a's said step-by-step movement is interrupted by the engagement of a link or lug 36 of the pattern chain with the projection 37 on the lever 38. In the event of such engagement of a lug 36 with the projection 37, the shaft is turned sufficiently to lift the arm or lateral projection 59 so that the latter will not be engaged by the constantly vertically moving rod 67.

The several selectin cams 21a to 25a are ada ted to'be moved inwardly with respect to t e needle cylinder, so as respectively to come under the butts upon the jacks 19, as

' already described with respect to Figs. 15

and 16. Said cams 21a to 25a are mounted upon a corresponding number or set of levers, one of which set of levers is shown at 80 in Fig. 8. In Fig. 8 said set oflevers is co-axially pivoted, as shown at. 81, to a block 82 on the lowerside of the cam block plate. In addition to the said tive levers, there is also one lever, indicated at 83 (see Fig. 7), which is connected lto the lowermost cam 20a to elevate all the jacks. Said cam 20a is not operated from any of the attern chains 28 to 32, but through independent connections to be hereinafter described.

The said cams 21a to 25a are respectively secured to the appropriate levers on the set of levers 80, as indicated in Fig. 8. As shown in said gures, each of the levers of the set of levers 80 is provided with a lug or lateral projection 84 adapted to be' moved b high lugs 84a upon the respective c ains 28 to 32, as clearly evident from Figs. 9 to 13. The engagement of one of the projec- 55 tions 84 by a high lug 84a on the correspondthe ing pattern chain moves the corresponding ppltern cams 21a to 25a radially outward.

en one of the Vprojections 84 slides off the high lug 84a, it will drop onto the link 841) of the chain, allowing the lever to move radially inward so as to take under the desired butts on the jacks, as hereinbefore described. The projection 84 will remain on the links 84?) for four courses and then will be raised by high lugs 84a.

We provide suitable means to withdraw from operative relation with the pattern chains 28 to 32, the corresponding cams 21a to 25a. Herein for the purpose we have mounted upon the creel rod 85, shown in Figs. 3 and 6, a ba'r 86 whose end 87, when swung to the left viewing Fig. 6, is adapted to strike all the levers 80 so. as to move them out of the range of said pattern chains. Said bar 86 is herein operated in the following manner.

The disk cam 88, shown 'in Fig. 5 as upon A the pattern shaft 9, is adapted to act upon a lever 89 to which is connected a long, upright rod or link 90 which, at its upper end, 1s plvotally connected at 91 to a bell crank 92 pivoted at 93 on the framing, and having connected at one end 94 thereof a link 95 which, as shown in Fig. 6, extends to the said bar 86 so as to operate the same at the desired times.

The purpose of the said bar 86 is either to throw all the way out all of the levers of the said set 80 in the heel and toe or to throw them part way out. The needles are arranged in a long butt series and a short butt series, and under the lon butt needles are long butt jacks, and un er the short butt needles are short butt jacks. ,When the bar 86 is moved to its greatest extent to the left, viewing Fig. 6, it moves the entire series of levers 80 suiiiciently far to withdraw all of the cams 21a to 25a from their jacks. When said bar 86 is positioned in an intermediate-position, it will so withdraw the cams 21a to 25a that said cams can act only upon the long butt jacks with the result that the stocking is made with a plain sole and diamond instep. I f it be desired to make a diamond sole and diamond instep, then the bar 86 would be moved to its outermost osition.

It is deslred to move out one of the stitch cams just as the` pattern is commenced. Viewing Fig. 7 the stitch cam thus to be moved out is that nearest the o rator who is facing the mechanism in Fig. In-said iigure, we have represented the said stitch cam as connected at 96 to a link 97 pivotally connected at 98 to the bell crank 99 itself pivoted at 100. Pivoted at 101 to said bell crank 99 is a vertical link 102, the lower end 103 whereof is connected to horizontal lever 104 whose opposite end 105 is pivotally connected at 106 to a vvertical link 107. The said constructionjs shown upon a smaller scale in Fig. 2, and in said Fig. 2 .the link 107 is shown as connected atits lowerend to a lever 108 riding upon the cam4 109 on the pattern shaft 9. 'By the described connection, the

front stitch cam is withdrawn from action f threads are to befedin a .plating relation to all the needles), it is necessary to elevate all Athe jacks.' In lthis embodiment of the invention,l this result is., obtained by moving inward theca'm-20a. so as to engage all the butts 2 0 on the jacks. While any suitable means may be employed for this purpose, we have herein vprovlded the following mechamsm.

To the lever 8,3 carrying theI cam 20a, as indicated in Fig'. 7, there is connected a link 110 which is connected to abell crank lever 111, shown most clearly in Fi s. Band 5, and indicated also ,in Fig.` 8. aid bell crank lever connectedI to an upright lon Alink 112 which, at itslower. end, is provide with a lever or member 113 to ride upon a suitable cam onthe v'pattern shaft 9,.whereby at the desired timeor times the said cam 20a is moved inward to elevate all the needles.

To move outwardl a stitch cam at the desired times, as at t e vcommencement of a pattern, we have connected thereto a link 115 see Fig. 7) pivotedto a-bell crank lever itsel pivoted at 117 and having an arm 116 to which `is ivoted an upright link 118 pivoted at itsV ower lend to a horizontal lever 119 which is pivoted at 120 and has connected to its opposite end an upright link 121 (see Figs. 6 .and 7), which extends downto the pattern chain mechanism by which it is connected, as by a lever at its ower end resting on said pattern chain mechanism.

Having thus described one illustrative embodiment of our invention, it is to be understood that although specific terms are employed, they are used ina generic and descriptlve sense and not for purposes of 11m1- tation, the sco e of the invention being set forth in the fo lowing claims.
